Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Beaten egg thickens the mixture and binds it with the ham.
Vinegar
Adds acidity that sharpens the flavour and balances the richness of the ham.
Mustard
Adds sharp, pungent flavour that cuts through the richness of the ham and butter.

The step that matters

Stir in the egg and mustard mixture. Egg thickens when heated and can curdle or scramble if added carelessly to hot vinegar. Adding it gradually while stirring keeps the mixture smooth.

Swap the mustard

How well each one fits the dish's main ingredients (bread, butter, ham, egg, vinegar):

  2. Shallotfits about as well
